Mic Level
This diagnosis screen allows you to independently test the microphone and the navigation TALK and navigation BACK buttons. They are used to activate the voice control system. The microphone is located near the map light in the ceiling. The microphone can now isolate the driver's voice even when there is noise or other conversations in the vehicle. To properly check the microphones, make sure you are sitting in the driver's seat.
- Press the navigation TALK button on the steering wheel, wait unit you hear beep and in a normal voice say "testing" The Talk indicator on the screen should momentarily turn green, and the text "Now Recording...", should appear in yellow. If the Mic Level indicator on the screen does not briefly turn green, check the wiring from the navigation TALK button to the navigation unit.
- If there is no Mic Level movement when you speak, then you should check the wire running from the microphone to the navigation unit.
- If the Mic Level bar is full or almost full without you speaking or other back ground noise, replace the microphone (ambient light) and recheck.
- Press the navigation BACK button on the steering wheel. This should cause the Cancel indicator on the screen to momentarily turn green. If it does not briefly turn green, then check the wiring from the steering wheel navigation BACK button to the navigation unit.
NOTE:
- The Mic Level indicator must reach the 6th bar or greater to pass the test.
- If the radio is off, and there is movement in the indicator-even without speaking, then ensure that the vents are not blowing on the microphone.
- This should resolve voice control complaints such as:
- sometimes the system does not understand my commands.
- I have to shout at the navi for a command to be recognized.
- The system just says "pardon".
